Abstract
1. Оправочный узел стана винтовой прокатки, содержащий охлаждаемую оправку с несквозной внутренней поверхностью, установленную на полом наконечнике, который зафиксирован на полом стержне, снабженном размещенной внутри него подводящей трубкой и свободно вставляемым в нее телескопическим патрубком, отличающийся тем, что на торце подводящей трубки, обращенном к оправке, жестко закреплен фланец, на концах телескопического патрубка жестко зафиксированы ограничивающие элементы, а в зазоре между подводящей трубкой и телескопическим патрубком размещена пружина сжатия.2. Оправочный узел по п.1, отличающийся тем, что ограничивающий элемент, зафиксированный на конце телескопического патрубка, обращенном к оправке, выполнен в виде стопорного кольца, а зафиксированный на другом конце патрубка - в виде упорной шайбы.1. The mandrel assembly of a helical rolling mill, comprising a cooled mandrel with a non-through inner surface mounted on a hollow tip, which is fixed on a hollow rod, equipped with a supply tube located inside it and a telescopic pipe freely inserted into it, characterized in that at the end of the supply tube, facing the mandrel, the flange is rigidly fixed, the ends of the telescopic pipe are rigidly fixed, and in the gap between the inlet pipe and the telescopic pipe The compression spring is located. 2. The mandrel assembly according to claim 1, characterized in that the limiting element fixed on the end of the telescopic pipe facing the mandrel is made in the form of a retaining ring, and fixed on the other end of the pipe in the form of a thrust washer.
